Hi all, does anyone know the best way to increase the grip size while keeping down the added weight to a minimum. I know the conventional way is to use either overgrips or a grip sleave, but has anyone ever tried other methods such as duct tape? I'm trying to increase my racket from a 3 to a 4, but the extra over grips have increased the weight to around 365g, which is not a proplem on groundies, but i've lost a bit of pop on my serves as the increased swing weight has decreased the racket head speed that i'm able to generate. Any input would be much appreciated, no mater how unconventional the method.
